We are required in this problem to approximate tan α which <span>α is less than </span><span>20 degrees.
In radians 20degrees is equal to 0.349; find tan 0.349=0.363
percentage error=(0.349-.363)*100/(0.363) =-3 percent error so for largest angle 20 degrees , the error is less than 10 percent</span>
Answer:
The maximum speed of the car is 31.46 m/s.
Explanation:
Given that,
Radius = 101 m
We need to calculate the maximum speed that the car can go over the hill without leaving the road
Using relation of normal force and centripetal force
Where, m = mass of car
Put the value into the formula
Hence, The maximum speed of the car is 31.46 m/s.
The answer is A. Thermal energy is transferred.
Good Luck!!!
Answer:
The displacements are not equal. While their direction is the same, their length (i.e., distance or magnitude) is not. A is longer than B.
